Preheat the oven to 200C/400F. Line a large baking tray with parchment paper and set aside.
In a large mixing bowl, add both kinds of flour, baking soda, and salt, and mix well.
In a separate bowl, combine the unsweetened almond milk and apple cider vinegar. Stir well and let it sit for a few minutes. This will create a vegan buttermilk that will help the bread rise and become tender.
Make a well in the center of the dry ingredients and pour in the vegan buttermilk mixture. Add the maple syrup. Stir the mixture until it comes together to form a sticky dough.
Gently knead the dough until smooth. Do not over-knead; the dough should be slightly sticky. Place the shaped dough onto the prepared baking sheet. Use a sharp knife to make a deep "X" on the top of the loaf. This helps the bread bake evenly and allows heat to penetrate the center.
Transfer the baking sheet to the preheated oven and bake for about 15 minutes at 425°F (220°C). Then reduce the oven temperature to 400°F (200°C) and continue baking for another 20-25 minutes or until the bread is golden brown and sounds hollow when tapped on the bottom.
Let the bread cool completely before slicing and serving.
